"The best settings possible" is very subjective. You've already got something decent going, so you're just going to have to play around with it.

I'm not sure how well that CPU performs, so it's hard to say whether you can bump up your x264 preset, but if you can run superfast or veryfast, that would be a big step up.

Even if you can't fun a better preset, you should still be able to increase your FPS to 30, which would be good.

Well then, try the things I suggested and see how it works. You'll have to play around with settings. Sorry, it's kind of hard to help you more than that.

"Just Try It!"
